NEW BRUNSWICK — Authorities are asking for the public’s help in finding the man who sexually assaulted a 24-year-old woman in New Brunswick in January.

Middlesex County Acting Prosecutor Andrew Carey said the suspect is described as a heavy-set Hispanic male with a dark complexion, between the ages of 30 and 40, 5-feet, 8-inches tall, with dark “spiked” hair and no facial hair. He was wearing dark pants and a black, zippered hooded jacket.

Carey said the man was last seen fleeing on Townsend Street toward Joyce Kilmer Avenue shortly after 2:30 a.m. on Jan. 31, 2014.

He said a woman was walking on Townsend Street between Livingston and Joyce Kilmer avenues when the man walked up to her, punched her in the face several times, improperly touched her and attempted to further sexually assault her. He fled when she kicked him and screamed, the prosecutor said.

The woman went to a residence, where neighbors called police.

Carey said anyone with information is asked to call county investigator James Kelly at (732) 745-3600 or New Brunswick police detective Ronoldy Martinez at (732) 745-5217.
